Considering its cold concrete and steel interiors, plus the complete lack of belongings, you'd instantly assume this Kyoto house was still being built. Yet, a family has inhabited it for a year now. Watch the odd video tour below.

Rising over Lucerne's lakeshore, Switzerland, the O House has views to the titanic Mount Pilatus and the mountains of Rigi and Bürgenstock. It's also full of holes, like some delicious Emmental, and has a 82-feet pool, half inside, half outside.
